What volume of acetylene is formed as a result of the interaction of 32 g of calcium carbide with excess water?

The reaction for the synthesis of acetylene from calcium carbide is described by the following chemical reaction equation:

CaC2 + 2H2O = C2H2 + Ca (OH) 2;

From 1 mole of calcium carbide, 1 mole of acetylene is synthesized.

Let’s calculate the available chemical amount of silicon carbide substance.

M CaC2 = 40 + 12 x 2 = 64 grams / mol;

N CaC2 = 32/64 = 0.5 mol;

The same amount of acetylene will be synthesized.

Let’s calculate its volume. To do this, multiply the amount of substance and the standard volume of 1 mole of gaseous substance. 1 mole of ideal gas fills a volume of 22.4 liters under normal conditions.

V C2H2 = 0.5 x 22.4 = 11.2 liters;
